Graduate Medical Education in Tactical Medicine and the Impact of ACGME Accreditation of EMS Fellowships.

Physician interest in tactical medicine as an area of professional practice has grown significantly over the past decade. The prevalence of physician involvement in terms of medical oversight and operational support of civilian tactical medicine has experienced tremendous growth during this timeframe. Factors contributing to this trend are multifactorial and include enhanced law enforcement agency understanding of the role of the tactical physician, support for the engagement of qualified medical oversight, increasing numbers of physicians formally trained in tactical medicine, and the ongoing escalation of intentional mass-casualty incidents worldwide. Continued vigilance for the sustenance of adequate and appropriate graduate medical education resources for physicians seeking training in the comprehensive aspects of tactical medicine is essential to ensure continued advancement of the quality of casualty care in the civilian high-threat environment.

Prehospital emergency care training practices regarding lesbian, gay, bisexual, and transgender patients in Maryland (USA).

INTRODUCTION: Prehospital Emergency Medical Services (EMS) providers are expected to treat all patients the same, regardless of race, gender identity, sexual orientation, or religion. Some EMS personnel who are poorly trained in working with lesbian, gay, bisexual, and transgender (LGBT) patients are at risk for managing such patients incompletely and possibly incorrectly. During emergency situations, such mistreatment has meant the difference between life and death. METHODS: An anonymous survey was electronically distributed to EMS educational program directors in Maryland (USA). The survey asked participants if their program included training cultural sensitivity, and if so, by what modalities. Specific questions then focused on information about LGBT education, as well as related topics, that they, as program directors, would want included in an online training module. RESULTS: A total of 20 programs met inclusion criteria for the study, and 16 (80%) of these programs completed the survey. All but one program (15, 94%) included cultural sensitivity training. One-third (6, 38%) of the programs reported already teaching LGBT-related issues specifically. Three-quarters of the programs that responded (12, 75%) were willing to include LGBT-related material into their curriculum. All programs (16, 100%) identified specific aspects of LGBT-related emergency health issues they would be interested in having included in an educational module. CONCLUSION: Most EMS educational program directors in Maryland are receptive to including LGBT-specific education into their curricula. The information gathered in this survey may help guide the development of a short, self-contained, open-access module for EMS educational programs. Further research, on a broader scale and with greater geographic sampling, is needed to assess the practices of EMS educators on a national level.

Medical support for law enforcement-extended operations incidents.

OBJECTIVE: As the complexity and frequency of law enforcement-extended operations incidents continue to increase, so do the opportunities for adverse health and well-being impacts on the responding officers. These types of clinical encounters have not been well characterized nor have the medical response strategies which have been developed to effectively manage these encounters been well described. The purpose of this article is to provide a descriptive epidemiology of the clinical encounters reported during extended law enforcement operations, as well as to describe a best practices approach for their effective management. DESIGN: This study retrospectively examined the clinical encounters of the Maryland State Police (MSP) Tactical Medical Unit (TMU) during law enforcement extended operations incidents lasting 8 or more hours. In addition, a qualitative analysis was performed on clinical data collected by federal law enforcement agencies during their extended operations. RESULTS: Forty-four percent of missions (455/1,047) supported by the MSP TMU lasted 8 or more hours. Twenty-six percent of these missions (117/455) resulted in at least one patient encounter. Nineteen percent of patient chief complaints (45/238) were related to heat illness/ dehydration. Fifteen percent of encounters (36/238) were for musculoskeletal injury/pain. Eight percent of patients (19/238) had nonspecific sick call (minor illness) complaints. The next most common occurring complaints were cold-related injuries, headache, sinus congestion, and wound/laceration, each of which accounted for 7 percent of patients (16/238), respectively. Analysis of federal law enforcement agencies' response to such events yielded similar clinical encounters. CONCLUSIONS: A wide range of health problems are reported by extended law enforcement operations personnel. Timely and effective treatment of these problems can help ensure that the broader operations mission is not compromised. An appropriate operational strategy for managing health complaints reported during extended operations involves the deployment of a well-trained medical support team using the core concepts of tactical emergency medical support.

Energy intake and expenditure profile in chronic peritoneal dialysis patients complicated with circulatory congestion.

BACKGROUND: Circulatory congestion is an adverse predictor of mortality in peritoneal dialysis (PD) patients. OBJECTIVE: This study evaluated the nutritional status, energy intake, and expenditure profile of PD patients with and without previous circulatory congestion. DESIGN: We conducted a cross-sectional study in 244 PD patients, of whom 92 had previous circulatory congestion. We estimated dietary energy intake by using a locally validated 7-d food-frequency questionnaire and by assessing resting energy expenditure (REE) and total energy expenditure (TEE) with indirect calorimetry and a locally validated physical activity questionnaire, respectively. RESULTS: In comparison with those without circulatory congestion, patients with previous circulatory congestion were more malnourished by subjective global assessment (59% compared with 36%; P < 0.001), had lower handgrip strength, had lower midarm muscle circumference, had lower dietary protein (0.98 +/- 0.45 compared with 1.19 +/- 0.44 g x kg(-1) x d(-1); P < 0.001), and had lower energy intake (92.5 +/- 37.0 compared with 110.9 +/- 35.7 kJ x kg(-1) x d(-1); P < 0.001) but had higher C-reactive protein (P = 0.025) and higher REE (P < 0.001). However, no difference in TEE was noted between the 2 groups, which indicated lower activity energy expenditure among patients with previous circulatory congestion. The resulting energy balance was significantly more negative for patients with previous circulatory congestion than for those without previous circulatory congestion (P = 0.050). Furthermore, the prevalence of malnutrition increased with increasing episodes of circulatory congestion (P = 0.017). CONCLUSIONS: Patients with previous circulatory congestion had significantly more inflammation, more muscle wasting, and higher REE but lower activity energy expenditure and energy and protein intakes in keeping with an anorexia-cachexia syndrome. The mechanisms of increased REE and reduced energy intake among patients with previous circulatory congestion warrant further investigation.

Older men with higher self-rated socioeconomic status have shorter telomeres.

BACKGROUND: previous studies examining the relationship between socioeconomic status and telomere length showed conflicting results, one study finding shorter telomere length in subjects with lower socioeconomic status and one showing no relationship. DESIGN: cross-sectional study. SETTING: community-living elderly Chinese in Hong Kong. OBJECTIVE: this study examines the relationship between self-rated social economic status and telomere length in Hong Kong Chinese men and women aged 65 years and over living in the community. SUBJECTS AND METHOD: information was collected from 958 men and 978 women regarding possible confounding factors such as the presence of chronic diseases, smoking, physical activity level, dietary intake and body mass index. Telomere length was measured by quantitative PCR. RESULT: in men only, after adjustment for age and other confounding factors, a higher ranking in community standing was associated with shorter telomere length. CONCLUSION: men with higher self-rated socioeconomic status have shorter telomeres, possibly mediated through psychosocial rather than lifestyle factors or the presence of chronic disease. There may be cultural ethnic and age-related differences in social determinants of health.

Resting energy expenditure and subsequent mortality risk in peritoneal dialysis patients.

Cardiovascular disease is the leading cause of death in ESRD patients and is strongly associated with malnutrition. The mechanism of malnutrition is not clear, but hypermetabolism is suggested to contribute to cardiac cachexia. This study examined resting energy expenditure (REE) in relation to the clinical outcomes of ESRD patients who receive continuous ambulatory peritoneal dialysis (CAPD) treatment. A prospective observational cohort study was performed in 251 CAPD patients. REE was measured at study baseline using indirect calorimetry together with other clinical, nutritional, and dialysis parameters. Patients were followed up for a mean +/- SD duration of 28.7 +/- 14.3 mo. REE was 39.1 +/- 9.6 and 40.1 +/- 9.0 kcal/kg fat-free edema-free body mass per day for men and women, respectively (P = 0.391). Using multiple regression analysis, fat-free edema-free body mass-adjusted REE was negatively associated with residual GFR (P < 0.001) and serum albumin (P = 0.046) and positively associated with diabetes (P = 0.002), cardiovascular disease (P = 0.009), and C-reactive protein (P = 0.009). At 2 yr, the overall survival was 63.3, 73.6, and 95.9% (P < 0.0001), and cardiovascular event-free survival was 72.3, 84.6, and 97.2% (P = 0.0003), respectively, for patients in the upper, middle, and lower tertiles of REE. Adjusting for age, gender, diabetes, and cardiovascular disease, patients in the upper and middle tertiles showed a 4.19-fold (95% confidence interval, 2.15 to 8.16; P < 0.001) and a 2.90-fold (95% confidence interval, 1.49, 5.63; P = 0.002) respective increase in the risk of all-cause mortality compared with those in the lower tertile. However, the significance of REE in predicting mortality was gradually reduced when additional adjustment was made for C-reactive protein, serum albumin, and residual GFR in a stepwise manner. In conclusion, a higher REE is associated with increased mortality and cardiovascular death in CAPD patients and is partly related to its close correlations with residual kidney function, cardiovascular disease, inflammation, and malnutrition in these patients.
